Complete 'django piston with oauth support' example
If you're using a released version of Piston, you might be interested in how we implemented OAuth in Snowy, our AGPL web app for Tomboy notes:
http://git.gnome.org/browse/snowy/tree/urls.py#n48
http://git.gnome.org/browse/snowy/tree/api/urls.py
http://git.gnome.org/browse/snowy/tree/api/templates/piston/authorize_token.html
http://git.gnome.org/browse/snowy/tree/api/handlers.py
The OAuth views are bundled with piston (in the released version).
I have yet to upgrade to prencher's improved OAuth fork (which will apparently turn into 0.3 soon?), but here are his instructions if you are using his code:

(make sure to read all of his responses in that thread, as he makes some clarifications)
